There is a great book called The Conspiracy Against the Human Race that talks about this in a way that makes sense to me:
As a survival-happy species, our successes are calculated in the number of years we have extended our lives, with the reduction of suffering being only incidental to this aim. To stay alive under almost any circumstances is a sickness with us. Nothing could be more unhealthy than to “watch one’s health” as a means of stalling death. The lengths we will go as procrastinators of that last gasp only demonstrate a morbid dread of that event. By contrast, our fear of suffering is deficient.
The book is very pessimistic but that’s the point, I quite enjoyed it.
